Abstract: PROBLEM TO BE SOLVED: To prevent the height from being increased to efficiency cool a heat generation object, while power consumption for cooling is saved for efficiently cooling the heat generating object of a CPU emitting a high temperature with the increase of power consumption for making performance high. SOLUTION: This cooling device 10 of a notebook personal computer is constituted by comprising a heat sink 14 which heat-conducts a part of heat emitted from the heat generating object 12 of the notebook personal computer to a position different from the heat generating object 12, a heat transfer means 16 which forcedly transfers the remainder of heat emitted from the heat generation object 12 to a position different from the heat generating object 12 and forcible heat generating means 22 and 28 which compulsorily radiate heat.
